Query Neo4j/AWS Neptune databases via an interactive console

options:
  -h, --help            show this help message and exit
  -q STRING, --query STRING
                        Cypher query to execute. If not provided, starts interactive console
  -d STRING, --db-uri STRING
                        Database URI
  -b, --benchmark       Benchmark query execution times without showing results (only applicable in query mode)
  -n INTEGER, --bench-num-runs INTEGER
                        Number of benchmark runs (default: 5)
  -W INTEGER, --bench-warmup-num-runs INTEGER
                        Number of warmup runs before benchmarking (default: 0)
  --debug               Print debug information without doing anything
  -w, --write           Write query results to file (or start console with 'write results' mode on)
  -f {json,csv}, --format {json,csv}
                        Output file format for query results
  -p, --print-query     Print the query (or start console with 'print query' mode on)

# Interactive mode
export DB_URI='bolt://127.0.0.1:7687'
export DB_USER='user'
export DB_PASSWORD='password'
graphc

graphc -d 'bolt://abc.xyz.us-east-1.neptune.amazonaws.com:8182'

# One-off query mode
graphc --query 'MATCH (n: Node) RETURN n.id, n.name LIMIT 5'

graphc -q - < query.cypher

echo 'MATCH (n: Node) RETURN n.id, n.name LIMIT 5' | graphc -q -

📟 Console

graphc comes with a console where you can execute queries in an interactive manner.

Commands

Keymaps

✏️ Write mode

graphc lets you save query results to a file in both one-off query mode and console mode.

cat query.cypher | graphc -q - --write

In console mode, use the command write <FORMAT> (format can be csv or json).

graphc will save results in the directory it's run in, in a subdirectory called .graphc.

🔢 Benchmarking

You can benchmark the execution times for a query using the --benchmark/-b flag.

cat query.cypher | graphc -c - -b -n 5 -w 2
